it feels like the transmission is slipping. but its not. my rpms dont drop. it doesnt do it when your idleing. just when your driving depending on how much gas you give her. i need help.

    More then likely the coils, had an '05 Durango 4.7L Friday with the same problem, weak coils, 5 of them.

    i was hoping not.. theyre 35 bucks a piece. it blinks five or six times when you really step on it.

    Yep and that's cheap compared to any of the others. I was surprised they weren't close to a hundred ea like the Kia.

    Without a scan tool and monitoring ignition or misfire data, I guess it will be trial by error, and switch them around one at a time until it stops missing. Get one new one and put it in on # 1, if it's better get another one and try the next one. If it doesn't get any better on #1 put it in # 3,and try that one, and so forth.

    ok. so just go down one side at a time untill it gets better. then if its not compleetly fine then get another one and continue on from the one thats been fixed.

    That's the only thing I know except if you have some one hold the brake pedal and raise the RPMs and it starts to stumble take the connector off one coil at a time and see if there is no change in engine while one is unplugged then that one could be bad. Change them to start but others might not show up until you drive it under the same conditions to verify it has stopped stumbling.

    Have Autozone read codes and post results! Should have a misfire code that will show problem cylinder(s)!
